[quote1277317830=PUGNACES-BRITANNIAE-AK] not every dog is like you want it to be. there are also weak nerved dogs by nature. for example lately i have showed a scared fila. i don´t think this dog was scared because his owner treated him in a bad way. [/quote1277317830] You are right, however, like in the video you mentioned, neither decoy OR handler were doing anything correctly, so it isn't surprising that the confused dog failed. I have always believed that genetic predisposition is about 30%, and the rest is nurture or the molding, or lack there of, of the expressed phenotype.
